Moreover, if there is >1 FreeBSD machine in network, it is really difficult to return network to normal behavior. The patch, I have sent (the last one), has been tested since PR open date till now on 2 big PPPoE concentrators serving 50 - 200 PPPoE clients each. -- Totus tuus, Glebius. GLEBIUS-RIPN GLEB-RIPE
